Abstract: A system (20) having the form of a garment (22), such as a jacket or pullover top, which can be transformed into one of a number of different fully closable containers (24), such as a rucksack, bag, or daypack, or vice-versa and a method for performing the transformation. Closure of the neck aperture (15) is operated by actuating a first closure means (1) extending from a common point (14) below the neck on the back of the body (R) of the garment, over the shoulders on either side of the neck aperture down the front (F) of said body.
